METALLIC SLEEPER FOR MECHANICAL TOY TRAIN-TRACKS.

Specification of Letters Patent.

Patented Au '.21, 1917.

Application filed January 10, 1917. Serial No. 141,714.

To all whom it may concern:

Be it known that 1, JOHN STAoK, a citizen of the United States, residingat 3628 N. Christiana Ave, Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Metallic Sleeper for MechanicalToy Train-Tracks, of which the following is a specification.

My invention relates to improvements in a metallic sleeper in which therails are held more rigid and permanent; and the objects of myimprovements are first, to provide for the rails being held centrallyand uniformly apart. Second, to aflord integral lugs to clamp the railsvtaut and which are indestructible. v

I attain these objects by the principles illustrated in the accompanyingdrawing in which:

Figure 1, shows the sleeper blank before being formed, and locations ofthe lugs.

Fig. 2, is the perspective view of a complete sleeper, showing the lugsopen at one end and closed in position at the other end.

Fig. 3, is the top view of a sleeper with lugs opened ready for theinsertion of the rails.

Fig. 4, is the side view of a sleeper with the rails inserted and lockedby lugs at one c113 and with the lugs left open at the other en Fig. 5,is the end view of a sleeper with its lugs open.

Fig. 2, A designates the inner lugs and A", the outer lugs, formedupward and then pressed downward, holding the rails centrally anduniformly apart.

The sleeper is composed of an outer metallic shell bent to an inverted Ushape in cross section. I

At points where the rails cross the shell a transverse slit is cutacross the top of the shell from edge to edge. Cuts are then made at theupper edges equidistant longitudinally of the shell from the slit thusforming two lugs and enabling said lugs to be bent upward at rightangles to the surface of said shell, Fig. 2 A

The transverse slit extends below the surface on the side walls of saidshell and from this slit and connecting with said slit is a triangularportion out out of the side wall of the shell about the size of the railflange,

thus forming two more lugs, Fig. 2, A, A and adapted to be bentoutwardly at right angles to the side wall of said shell, and providinga recess for the rails to the vdepth beyond the rail flange. Similarlugs are formed on the opposite side.

After the rails are set in place the upwardly bent lugs are turned backabutting the web of the rails from both sides; and. the outwardly bentlugs of the side wall are turned back, their lower edges extending overthe rail flange and their front edges abutting the web of the rails,thereby producing a substantial track, in which the rails are heldcentrally and uniformly apart.

I am aware that metallic sleepers have been made prior to my invention.I therefore do not claim such a sleeper so broadly, but

7 I claim:

In a sleeper of the character described a body portion bent to form aninverted U shaped shell, a plurality of slits formed near the ends ofthe shell, lugs formed by the slits and adapted to be bent upwardly atright angles to the surface of the shell, and lugs formed and adapted tobe bent outwardly at right angles to the side walls of said shell,providing recesses for the rails, the said lugs at right angles to thesurface of said shell being adapted to be bent back with their frontedges abutting the web of the rail, and cooperate with thefirst-mentioned lugs to hold the rails in position.
